Since it has been used for many years, there are no improvement points. The sound of when putting in the file and closing it, the clicking and closing sound are the best for this product. Also, even if you put a lot of files, paper is not apt to twist. We will continue to use it.

Although I did not use the impression that I used, I ordered it on Sunday afternoon, and arrived on Tuesday 2 days after arrival. Honestly I think that it is earlier than others. It was saved. Thank you!
